Haven’t seen it, at least not more detailed than COL comparison. Would be a very useful tool, and hardly a heavy lift. Strikes me as some census data, and a (complex, but still) SELECT… WHERE;
Similar things have crossed my mind to build.
Betteridge’s Law of Headlines - I find it has near universal applicability.
If their comfort level is limited due to lack of experience, I tend to sandbox them somehow and then walk them through a couple examples of “danger” vs “ok, this definitely won’t be irreversibel if it’s wrong, but I think it will do what I want.”
A couple of my go tos are the obvious rm -rf / vs ./ and a sed with and without -i on some random text file.
That naturally segues to “here’s the man page, here’s how to use it and search it.”
That tends to give them some confidence that they won’t accidentally cause real damage, and make it seem like they aren’t just typing arcane magic spells, but actually understanding how to responsibly put the pieces together.
I’m not sure I agree - your definition would almost certainly include the kernel, office suites, and a host of other things.
I like that. It seems the internet with theoretically good answers for things that can be difficult to find. Blog format is much easier to skim that SO, and as long as the post titles are valid and meaningful, it’s a quick check for usefulness before reading.
